WHAT CAUSES THE NORTHERN LIGHTS?

The Northern Lights otherwise known as Aurora Borealis are created when sun's ionic particles are exerted and move toward the Earth's North and South poles. Because of the speed, the sun particles knock electrons out of atoms in our atmosphere. These electrons then knock into other atoms, causing colors in the sky, often green.

The lights are visible when skies are clear from clouds near the north and south poles. The Northern Lights are seen from Northern Scandinavia, Iceland, Alaska, Canada, southern Greenland, and northern Siberia. The Southern Lights primarily are seen from Antarctica, but potentially are seen from New Zealand and Tasmania.
